The comparison between hoolock and black gibbons showed that hoolock song had a longer duration and a wider range of the time distribution, with significant difference. 与黑长臂猿的种间比较表明,白眉长臂猿的鸣叫声在时间分布上有较大的散开度,持续时间也较长,二者有显著差异。
Reproduction of hoolock gibbon held in captivity 笼养白眉长臂猿的繁殖初探
Habitat Use of the Hoolock Gibbon ( Hoolock hoolock) at Nankang, Mt. Gaoligong in Spring 高黎贡山赧亢白眉长臂猿春季栖息地利用
The family group of Hoolock gibbons ( 1 ♀ 1 ♂) was observed and the data of their daily feeding amount were recorded by the focal animal sampling method in spring and autumn from 2007 to 2008. 野外于2007年–2008年春、秋季以焦点动物取样法观察同一家群(1♀1♂)白眉长臂猿,记录日取食量相关数据。
The size of individual between male and female, energy costs, food characteristics and requirements of physiology were factors impacting the daily feeding amount of Hoolock gibbon. 雌雄个体大小差异、能量消耗、食物特征、动物生理需求等因素影响白眉长臂猿的日取食量。
Food samples of Hoolock gibbon ( Hoolock hoolock) were collected at Mt. Gaoligong in Dec 2007 and Apr 2008. 2007年12月及2008年4月,在高黎贡山赧亢生境走廊带采集白眉长臂猿的食物样品。
Analysis showed that the population of Hoolock gibbon in the theoretical value and actual value of a gap in Nan Kang; Food availability of Hoolock gibbon does not limit the reasons for its population development in Nan Kang. 分析表明,赧亢白眉长臂猿种群数量的理论值和实际值有差距;赧亢白眉长臂猿食物可利用性并非是限制其种群发展的原因。
Hoolock gibbon depended on and preferred for the tall arbor. Less use of understory by hoolock gibbon was related to homogeneous of vegetation and the lower degree of human disturbance. 白眉长臂猿对高大乔木具有依赖性和选择偏好,对林下竹灌层的选择不高与植被分布均匀和人为干扰强度较小有关。
Rattans provide traveling connection between arbor forests and shrubs for hoolock gibbons. 藤本植物为白眉长臂猿在乔灌层之间活动提供了连接纽带。
The results of regression analysis showed that liane density and slope were the main factors affecting the habitat use by hoolock gibbon at Datang in spring. 回归检验结果显示,坡度和藤本密度为影响大塘片区白眉长臂猿生境利用的主要因子。
Facing the human disturbance in different intensity, hoolock gibbon between Datang and Nakang expressed different adaptive behavior. 对不同强度的人为干扰,大塘和赧亢的白眉长臂猿表现出适应性差异。
The vegetation inhabited by hoolock gibbon was homogeneous at Datang region. 在大塘,白眉长臂猿适宜栖息的植被有较高的均匀性。
After comparing eight ecological factors relating to structure of vegetation used by hoolock gibbon between Datang and Nakang, the results indicated that suitable habitats were fragmentized in Nankang, whereas homogeneity and integrality of vegetation was better in Datang than in Nankang. 比较两地白眉长臂猿对与植被结构有关的8个生态因子的利用结果提示,赧亢适宜白眉长臂猿栖息的生境呈破碎化分布,而大塘的植被均匀性和完整性较高。
In order to protecting, restoring and effective management of Hoolock gibbon ( Hoolock hoolock) population. 为了白眉长臂猿(Hoolockhoolock)种群保护、恢复及有效管理。
According to the analysis results of topographical factors, hoolock gibbon in both Datang and Nakang had the same requirement for avoiding wind and preferring sun-facing slope. 据地形因子分析结果,大塘和赧亢的白眉长臂猿对避风和趋阳坡有共同需求。
